CARPENTERS BENCH VISE.

Application filed May 13,

My invention relates to a carpenters bench vise shown in the accompanying drawings and more particularly described in the following specification and claims.

The primary object of my invention is to provide a device which may be removably attached to a carpenters bench to grip and hold wooden strips for planing or other tool operations, the construction being such that the gripping jaws may be raised or lowered for different widths of material and which will automatically adapt itself for wood of varied thicknesses,-the thrust of the plane upon the Wood serving to automatically cause the device to more firmly grip the work. V

A further object of the invention is to provide a device of simple and inexpensive construction which may be attached to a carpenters bench by merely sawing an opening in the top of proper size to accommodate the base plate, the arrangement being such that it may be left permanently attached to the bench but as it is customary in building operations for carpenters to constructa temporary bench upon which to do their work while the building is being erected, the device may be easily removed from the tempo rary bench and installed elsewhere when the work is completed.

lVith the foregoing and other objects in view which will appear as the description proceeds the invention further resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed it being understood that changesmay be made in the precise embodiment of the herein disclosed without departing from the spirit of the same.

In the drawings accompanying this speciiication: r

Figure 1 is av fragmentary cross sectional perspective view of a bench showing the device attached thereto, and in dotted lines a wooden strip gripped between the jaws of the device.

Figure 2 is a perspective view of the base plate showing it as it would appear detached from the bench.

Figure 3 is a perspective View of a vertically adjustable U-shaped sleeve adapted to be supported in the base plate at varying altitudes, the sleeve being constructed with an integral stationary gripping jaw.

ed to engage the side of a. piece to be held and to force it into impinging relation with the stationary jaw of the sleeve.

Figure 5 is a fragmentary perspective View of a carpenters bench showing the device attached thereto, with a wooden strip gripped by the vise in position to be planed.

Referring now to the letters of reference placed upon the drawings: i

A denotes a carpenters bench of usual construction provided with an opening in its top to receive the depending Walls B 13* of the base plate B, secured to thebench by screws extending through apertures bfpro vided in the plate. i

As indicated in Figure 2 the depending wall B of the base plate is inclined toward the opposing wall B and the end of the walls at the open end of the base plate are provided with vertical opposing flanges 13, 13", adapted to overlap the edges of a vertically adjustable U-shaped sleeve C;-the outer faces of the depending walls of which conform to the walls 'B and B of the base )late. The U-shaped sleeve C has a flange overlapping the base plate B when in its lowermost position and it is provided on one side with a wall C inclined to the opposing depending wall of the sleeve, forming a stationary jaw for engaging the wooden strip lV, held by the device; The top of the jaw C is below the plane of the upper face of the flange C and is on an even plane with a ledge C forming the upper edgeof the opposing wall,the two surfaces uniting to provide a supporting ledge for the adj ust- I able jaw D which at the top is constructed with a flange D overlapping the flange C of the'sleeve. It also has a transverse arm D 'resting upon the ledge formed by the jaw C of the sleeve. The adjustablejaw Dhas also a vertical ledge or abutment D, ext-endinglaterally from its side wall against which the end of the wooden strips W bear.

It will be noted that the vertical edge C above the ledge C is at-an angle to the stationary wall C of the sleeve and that the movable jaw D is forceddue to the thrust' of the wood piece against the abutment D,toward the face of the stationary jaw C thus gripping the wooden strip W between the jaws D and U, while the act of planing the piece will automatically tend to tighten the grip of the aws upon the strip.

To provide for holding wooden strips of varying widths, the sleeve C may be raised vertically and held in its adjust-ed position by the manually operated lever E pivoted at e to the base plate,-the engaging end of the lever E being shifted toward the adjustable sleeve C and into any one of several slots 0 provided in the outer face of the wall of the sleeve. E is a handle raised above the plane of the lever to facilitate the manual operation of the latter.

Having now indicated the several parts by reference letters the construction and operation of the device will be readily understood.

To install the device on a carpenters bench, a suitable opening is first cut in the top of the bench to receive the depending walls B and B of the base plate B. The base plate is then secured to the bench by screws extending through apertures b in the. flange in the base plate. The adjustable sleeve C is then inserted in the base plate and vertically adjusted to accommodate the width of the wooden strips TV to be planed. The lever E is then actuated so that its upturned engaging end 6 will enter the slot 0 to supportthe sleeveat the proper altitude. The adjustable jaw D is then inserted in the sleeve 'C,its flanges D D resting upon the ledges formed by the side walls of the sleeve. A wooden strip W to be planed is then inserted between thestationary jaw C of the sleeve and the adjustable aw D,the end of the strip bearing against the ledge I) of the adjustable jaw.

As the strip is forced toward the closed end of the sleeve, the adjustable jaw is crowded toward the stationary jaw by the inclined edge C of the sleeve,'as will be readily understood,-the thrust of the plane serving to tighten the grip of the jaws upon the piece being planed.

Having thus described my invention what I claim is:

1. A device of the character described comprising a supporting base having spaced walls; a vertically adjustable sleeve supported between the walls of the. base having a fixed gripping aw proj ectingbetween the walls of the sleeve; and an adjustable slidingfgrippingjaw supported within the sleeve upon an inclined guide-way formed in the wall of the sleeve directed toward t-he stationary aw, whereby the adjustable sliding jaw "will be forced along theinclined way of the sleeve toward the fixed jaw of the sleeve to grip the sides of an element held between the fixed jaw and the adjustable J 2. A device of the character described comprising a supporting base having spaced walls; a vertically adjustable sleeve supported between the walls of the base having a fixed gripping jaw projecting between the walls of the sleeve; and a slidable co-operating gripping jaw supported within the sleeve upon a guide-way inclined toward the stationary jaw and upon a ledge formed by said jaw,whereby the sliding jaw when adjusted will be forced along the inclined guide-way of the sleeve toward the fixed jaw to grip the sides of an element held between the Fixed and adjustable jaws.

3. A device of the character described comprising a supporting base plate with spaced walls depending therefrom; a vertically adjustable sleeve supported between the walls of the base plate having a gripping jaw integral therewith projecting between the spaced walls of the sleeve; means for supporting the sleeve at varying altitudes to the base plate; and an adjustable sliding gripping jaw supported within the sleeve upona guide-way formed in the walls of the sleeve inclined at an angle to the integral stationary jaw, said adjustable gripping jaw having an abutment to receive the end thrust of a work-element, gripped between the adjustable jaw and the jaw integral with the sleeve, whereby the adjustable sli-ding jaw will be forced along said inclined guide-way toward the integral jaw, to grip the sides of the workelement.

4t. A device of the character described comprising a supporting base plate with spaced walls depending therefrom; a vertically adjustable sleeve located between the walls of the base plate having a gripping jaw integral therewith projecting into the space between the walls of the sleeve; a manually operated swinging lever pivoted to the base plate, the free end of the lever being adapted to enter one of a plurality of recesses formed in the wall of the sleeve to support the sleeve-at varying altitudes to the base plate; and a slidable co-operating gripping jaw supported within the sleeve on a guide-way inclined toward the stationary jaw.

In testimony whereof, I sign this specification.
